Wonderful AC

This AC is great! It is so quiet, perfect for my living room. I really appreciate being able to control the unit on the app on my phone so I can make adjustments for my dog or turn it back on before I get back from a trip so my apartment is cool by the time I get home. This along with my air purifier were well made purchases from Windmill.

Great air conditioner!

Bought a Windmill for our bedroom window to augment a dying central air system this past summer. Very happy with our choice!Installation is easy. If you've installed other air conditioners, you can definitely install a Windmill. If you haven't installed an air conditioner before, the Windmill is very approachable and the very clear instructions take any guesswork out of the process.This is a design-forward product, and I do appreciate the thought that was invested in its appearance. Certainly more attractive than most window air conditioners, both inside the house and outside. Not an eyesore!It's straightforward to operate, and I found the smart/connected functionality to be quite welcome and useful. Overall, it's worth the investment, easy to live with, and even easier to recommend!

Great choice!

I love my Windmill AC. It looks so much nicer than most A/C's, it can be co trolled by my phone, and it cools quickly! The only down side is that it would vibrate at certain points when running, but thst was easily rectified by placing a wedge in the window (I used a piece of wood cut to size). It gave enough pressure on the window to stop the rattle.

love my upgraded AC!

I've been using windmill ACs for several years now, and a major plus is that I can control the unit via the phone app even when I'm not home. Not only does it work well, the design of the AC looks beautiful in my apartment. I used the original model (6k BTU) for 3 years, but after moving last year I decided to get the new WhisperTech model (8k BTU) and am super impressed with how much quietier it is and how quickly it cools my home. The customer support has always been fantastic as well!

Best A/C I've ever had!

This A/C unit is a powerhouse. It has turned my living room into the perfect place to be on a 90+ degree day. Within an hour of turning it on, my room is nice and cool and ready to relax in. The best part about it is that I can turn it on and off remotely from anywhere, so when I've had a long day at work, I turn it on when I am headed home and the room is perfect when I arrive. I would highly recommend it to anyone!

We live in Oregon & till recent years never needed air conditioning. We own a small motel near Crater Lake.We now have 3 Windmill AC units in our house/office alone. The are easy to install and operate.They keep us, our guests, and most importantly our fur babies super comfortable all summer.We will always come back to this brand. Thanks much!

Very quiet

We needed a better AC to cool our first floor area and our old one was so loud and inefficient. I saw an ad for Windchill and figured we give it a try. Needless to say I want to purchase more to put in other areas of my house. Really glad I got one! Highly recommend.

Double Happy

I purchased not just one but two Windmill air conditioners. After my first purchase of a 12K BTU WhisperTech for my living room, I followed with an additional purchase of a 10K BTU WhisperTech for my bedroom. They are super efficient and oh so quiet. Also they are so good looking too. So happy with my purchases. Highly recommended.

Great AC unit with smart features and easy installation!

This AC unit was so easy to install and was so quiet that I ended up buying a second one for my son's room. I bought the smallest one for his room and its so quiet and perfect for his small nursery. Also that fact that I can control the AC unit from my phone helps when the temperature changes drastically in his room and I don't have to sneek into his room while hes asleep. Wonderful unit!

Excellent Unit

I have purchased 4 units for my home and an air purifier. All are aesthetically pleasing and efficient. They are quiet, sleek and keep our home comfortable! Being able to use the app before getting home has been key, as I don't need to waste electricity keeping them on all day. I have recommended to family members and friends.
